This study sought to uncover memorized algorithms and procedures that students relied on in responding to questions based on the particulate nature of matter (PNM). We describe various memorized algorithms or processes used by students. In the study, students were asked to balance three equations of chemical reaction and then draw particulate…

Advances the thesis that philosophical questioning should precede or accompany children's participation in science activities in the elementary grades. (CP)

Describes how an elementary teacher can incorporate science into the classroom even if he/she feels unsure in the realm of science. Emphasis is on using processes of science. (SA)

Introduces a role playing activity that actively engages students in the learning process of mitosis. Students play either chromosomes carrying information, or cells in the cell membrane. (Contains 11 references.) (Author/YDS)

Describes an open-ended, inquiry-based chemistry lab in which students design and construct snow globes. Encourages the development of problem solving skills. (DDR)

Introduces the computer software program Learning and Understanding through Computer-based Interactive Discovery (LUCID) which is designed to increase student engagement in the learning process. Evaluates the effectiveness of LUCID on student attitudes and grades. (YDS)

Students frequently misconceive the process of problem-solving, expecting the linear process required for solving an exercise, rather than the convoluted search process required to solve a genuine problem. In this paper we present an activity designed to foster in students realization and appreciation of the nature of the problem-solving process,…

Discussed is the teaching method called the learning cycle and how it can be incorporated into science activities. Included are examples of how teachers and students can use the learning cycle to produce instructional materials. (KR)

This paper describes how the learning cycle leads students to become more skilled reasoners. The three phases of the learning cycle are described and examples and goals of each are provided. Information is also offered on the three types of learning cycles: the descriptive; the empirical-inductive; and the hypothetical-deductive. Each is described…

Argues that cookbook chemistry laboratory experiments do little to teach scientific inquiry. Suggests providing students with laboratory experiences that follow the introduction of a concept and challenge students to investigate that concept through an experiment involving very few initial instructions. Lists some such challenges used in chemistry…

Three learning activities--story generation, reasoning from historical information, and computer modeling--that are designed to help students move toward a more coherent understanding of biological mechanisms are described. A method used to measure a student's level of understanding and their progress during instruction is also described. Ways to…

The teacher's role in directing science activities is examined in this book. Suggestions are offered on what teachers might do with the activities and advice is given on how the activities could be used. Each of the eight chapters contains a brief summary at the beginning, a detailed review at its close, and a list of specific guidelines for…

Discusses a unit to teach reasoning and problem solving skills by helping students develop a systematic approach to problem identification, gather and analyze data, arrive at inferences and keep from jumping to conclusions. Describes the development of an activity investigating liquids designed to foster the needed problem-solving skills. (JM)

Higher order cognitive development and success in the study of high school mathematics and science require an understanding of rational number concepts and facility with proportional reasoning and computation. Proportional reasoning is an essential schema for developing formal operational thought. This study involving 16 ninth-grade students was…

The intent of this book is to provide the framework for educational experiences designed to develop creativity, self-reliance, and a sense of independence in the students' approach to learning. It is comprised of eight units on a variety of themes. Each unit stresses the use of thinking processes, such as creativity and problem solving. Emphasis…
